Download or read book Euphorbia in Southern Africa written by Peter V. Bruyns and published by Springer Nature. This book was released on 2022-07-18 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a new account of Euphorbia in southern Africa. Euphorbia is the second largest genus of plants in the world. Southern Africa enjoys a high diversity in Euphorbia and 170 species occur here naturally. Of these 170 species, 128 or 74% are endemic. Where most species of Euphorbia in the northern hemisphere are herbs or shrubs, most of those in southern African are succulent. These succulents range from small, almost geophytic forms where the tuber is larger than the above-ground parts to huge trees 6 to 15 m or more in height. Many of them are spiny. There are also small numbers of herbaceous species in southern Africa and many of these are also dealt with here. The last account of the succulent species for southern Africa was published in 1941 and much new data has accumulated since then. Our understanding of the relationships of the species in Euphorbia has also been greatly enhanced by recent analyses of DNA-data, which led to new and unexpected results. From this new information an entirely new classification was developed, in which Euphorbia was divided into four subgenera. This provides the taxonomic framework for the presentation of our species here. Around ten new species have been described and these are presented in detail for the first time. This monograph is made up of two volumes. Volume 1 contains an extensive introductory chapter with an overview of the genus in the region, emphasizing many of its important and distinctive features. This is followed by Chapter 2, which deals with subgenus Athymalus. Of the four subgenera, this one is by far the most diverse in southern Africa, with 80 species. Volume 2 contains Chapters 3 (subg. Chamaesyce, 34 species), 4 (subg. Esula, 11 species) and 5 (subg. Euphorbia, 45 species), as well as an additional Chapter 6 covering the remarkable diversity of subg. Euphorbia in Moçambique. Each of Chapters 2 to 5 includes a key to all the species, followed by an account of each of them. This account includes synonymy, a description, data on distribution and habitat, line-drawings of floral features and other diagnostic details, notes on how the species is distinguished from its closest relatives and a brief history of its discovery. Several colour photographs are included for each species, illustrating its habitat, vegetative habit and flowering features, demonstrating key points distinguishing it from others and often showing its variability. Euphorbia is an important component of the vegetation in many of the drier parts of southern Africa. This book is based on a thorough evaluation of the vast herbarium record for southern African members of Euphorbia, on the extensive field-work conducted in the region and the wide taxonomic experience of the author. It is believed that both the professional botanist and the layman will find much that is new and informative in this monograph.

Download or read book Handbook of Alien Species in Europe written by Delivering Alien Invasive Species and published by Springer Science & Business Media. This book was released on 2008-11-14 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological invasions by alien (non-native) species are widely recognized as a significant component of human-caused global environmental change and the second most important cause of biodiversity decline. Alien species threaten many European ecosystems and have serious environmental, economic and health impacts. The DAISIE (Delivering Alien Invasive Species Inventories for Europe) project has now brought together all available information on alien species in Europe (terrestrial, aquatic and marine) and from all taxa (fungi, plants, animals). Thus for the first time, an overview and assessment of biological invasions in the Pan-European region is finally possible. The Handbook of Alien Species in Europe summarises the major findings of this groundbreaking research and addresses the invasion trends, pathways, and both economic as well as ecological impact for eight major taxonomic groups. Approximately 11.000 alien species recorded in Europe are listed, and fact sheets for 100 of the most invasive alien species are included, each with a distribution map and colour illustration. The book is complemented by a regularly updated internet database providing free additional information. With its highly interdisciplinary approach, DAISIE and its Handbook will be the basis for future scientific investigations as well as management and control of alien invasive species in Europe.

This authoritative lexicon is much more than a dictionary. It includes historical and linguistic information on botany and medicine throughout each volume.
Download or read book 1997 IUCN Red List of Threatened Plants written by World Conservation Monitoring Centre and published by IUCN. This book was released on 1998 with total page 934 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the most comprehensive compilation of data on threatened vascular plants ever published. It includes the names of some 33,000 plant species determined to be rare or threatened on a global scale. Conservation assessments were provided by the IUCN Species Survival Commission, the National Botanical Institute (South Africa), Environment Australia, and CSIRO, The Nature Conservancy, the Smithsonian Institution, and the Royal Botanic Gardens, Kew, together with hundreds of botanic gardens and botanists throughout the world. The Royal Botanic Gardens Edinburgh and the New York Botanical Garden have made major in-kind contributions.The result of 20 years work by botanists and conservationists around the world, it is intended as a conservation tool, a provider of baseline information to measure conservation progress and as a primary source of data on plant species. Most importantly, however, it provides the building blocks on which to base a worldwide effort to conserve plant species.
Download or read book Plant Ecology in the Middle East written by Ahmad Hegazy and published by Oxford University Press. This book was released on 2016-01-14 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: This advanced textbook explores the intriguing flora and plant ecology of the Middle East, framed by a changing desert landscape, global climate change, and the arc of human history. This vast region has been largely under-recognized, under-studied, and certainly under-published, due in part to the challenges posed to research by political disputes and human conflict, and a treatise on the subject is now timely. The book integrates Middle Eastern plant geography and its major drivers (geo-tectonics, seed and fruit dispersal, plant functional types, etc.) with the principles of plant ecology. The authors include the many specialized adaptations to desert and dryland ecosystems including succulence, water-conserving photosynthesis, and a remarkable range of other life history strategies. They explore the formation of 'climate relicts', and describe the long history of domestication in the region together with the many reciprocal effects of agriculture on plant ecology. The book concludes by discussing conservation in the region, highlighting five regional biodiversity hotspots where the challenges of desertification, habitat loss, and other threats to plant biodiversity are particularly acute. Plant Ecology in the Middle East is a timely synthesis of the field, setting a new baseline for future research. It will be important reading for both undergraduate and graduate students taking courses in plant ecology, evolution, systematics, biodiversity, and conservation, and will also be of interest and use to a professional audience of botanists, conservation biologists, and practitioners working in dryland ecosystems.

Download or read book The Soil Seed Banks of North West Europe written by Ken Thompson and published by Cambridge University Press. This book was released on 1997 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Buried viable seed banks are a fundamental aspect of seed plant biology. They play a key role in the conservation and restoration of plant communities and the response of plants to changing land use and climate. There is almost no area of plant ecology in which seed banks are not implicated. Despite several recent reviews of the ecology of seed banks, there has previously been no single source of data on seed persistence in individual species. This volume, which compiles the available data from the nineteenth century up to the end of 1993, provides this source for the 1189 members of the northwest European flora. The text describes the criteria for inclusion of data and discusses seed classification systems, the relative representation of different habitats, methods and taxa, and challenges for future research. Includes PC disc with database in searchable format.
Download or read book Waterwise Gardening in South Africa and Namibia written by Ernst van Jaarsveld and published by Penguin Random House South Africa. This book was released on 2013-10-29 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants that are indigenous to an area do not need additional watering; they are automatically adapted to the prevailing climate and weather conditions and are able to thrive under all but the most exceptional of circumstances. Gardening in harmony with nature means no longer having to provide the soil conditions and amount of water that non-indigenous species require. Waterwise Gardening in South Africa and Namibia is aimed at anyone who wants to create a new garden or convert an existing one to waterwise principles. The first part of the book focuses on general horticultural practises, such as creating the right type of garden for your climate and the best time to plant or prune. Part two details various garden types, based on South Africa's vegetation regions: Fynbos, Strandveld-fynbos and Succulent Karoo for the winter rainfall areas; Highveld, Bushveld, Thicket and Karoo for the summer rainfall regions. The forests and coastal belt of the Indian Ocean seaboard are covered, as are the Namib and adjacent desert areas, and indigenous indoor plants. For each region, representative lists of plant species are presented in categories such as trees, shrubs, perennials, architectural plants, succulents etc, with notes on plant form, height and growth rate, flower colour, months in flower and whether they prefer sun or shade.
